East Africa Resources Limited (ASX: EAF) is focused on developing uranium and gold projects in Tanzania. Through the acquisition of Tanganyika Uranium Corp (TUC), East Africa Resources has interests in two very large and prospective uranium exploration assets - Madaba-Mkuju and Eastern Rift - and is commencing initial exploratory work on both of these properties.

Madaba-Mkuju Project

Madaba covers approximately 950km2 and has targeted sandstone roll-front style uranium mineralisation. Prospecting licences and 29 applications in south-eastern Tanzania form the Madaba-Mkuju Property. The licences are located approximately 225 kilometres southwest of the business and commercial centre of Dar es Salaam.

The current exploration target area at Madaba was previously accessed by a combination of paved and seasonal 4WD roads leading south from Dar Es Salaam. The best access to the property is by helicopter from Dar es Salaam.

Sandstone-type uranium mineralisation at the Madaba-Mkuju Property was discovered in 1978 from ground follow-up of airbourne radiometric anomalies generated by German company, UEB. A total of 28 drill holes with available data were completed in 1981, with 15 of them penetrating the favourable sandstone horizon. Of these 15 holes, the average grade was 0.05% eU3O8 across thicknesses of 0.5 to 5.0 metres. The drilling tested an area of 30 km2 by 10 km2, averaging one successful hole per 20 km2. There has been no additional drilling completed since 1981. Potential for much higher grades in roll fronts developed in reduced areas. The Madaba-Mkuju Property has excellent geological potential for additional discoveries of sandstone-hosted uranium mineralisation.

The only known uranium exploration target within the package is at Madaba, where primary uranium-bearing horizons have been traced by 28 historic drill holes over a 300km2 area with the closest hole spacings ranging from 0.5 to 3.0 km apart and mineralised thicknesses ranging from 0.7 to 12 metres.

The Mkuju uranium occurrence not on ground covered by East Africa Resources now has a resource of 16 million kg of U3O8 at an average grade of 409 ppm. There is insufficient data to allow a direct stratigraphic correlation between the known mineralised zones at Mkuju and the Selous Property, but the geological, structural and geochemical settings are consistent.

Eastern Rift Project

Eastern Rift covers an area of 2,420km2 and has targeted calcrete-style uranium mineralisation. It comprises eight prospecting licences in northern Tanzania, located between Arusha and Tabora, approximately 250 kilometres north of the capital of Dodoma and 500 kilometres northwest of Dar es Salaam. The current prime exploration target at Mto wa Mbu is accessible by paved road 120km from Arusha and a network of gravel roads and trails suitable for 4WD vehicles provide access throughout most of the remaining Property area. Accommodations and basic provisions are readily available in Arusha. Domestic grid electricity is available at the villages of Mto wa Mbu and Minjingu.

The earliest reported mineral exploration and development activity in the area was in 1956, when New Consolidated Goldfields Ltd. discovered phosphate mineralisation at Minjingu. Further studies on the Minjngu phosphate deposits were carried out by the Japan Consulting Institute, Geomin, Kloeckner Industrieanlagen and Stamico. Country-wide airbourne radiometric surveys completed in the late 1970s and detailed surveys completed by Tanganyika in 2008 have identified numerous radiometric anomalies, including multiple anomalies on ground now covered by the Eastern Rift Property.

An uranium-prevalent radiometric anomaly over 14 km long is located almost entirely within the current boundaries of the Eastern Rift property and it has not been tested by pitting or drilling by TUC. Additional radiometric anomalies are also known on the Eastern Rift Property and have not been followed up.

While uranium mineralisation has not been identified to date, the anomalous uranium channel radiometrics and the geological environment favourable for calcrete-style uranium mineralisation suggest sub-surface uranium concentrations east of Lake Manyara.

The prime exploration target at Mto wa Mbu is located on PL 5654/2009. With uranium dominating potassium and thorium, part of the anomalous zone trends northeast off the project area but over 14 km of the strike of the anomaly occurs within the Eastern Rift Project.

The size and shape of Mbu wa Mbu has been likened to the anomaly at the 52 million kg (115 million pound) Yeelirrie uranium deposit.
